Diode and Continuity values from the datasheet:Be careful with the Siglent SDM3055, the continuity test is at about 6 or 7V.
good choice, one day I will get 6 1/2 or 7 1/2 digit Keithly but bench scopes can be handy just to keep things moving. Always on and in the right place. I have 8 DMMs and find it a pain to go find one when I need one on the bench. 50k count is reasonable. As the ADC gets higher, they get slower. I believe the data logging might be useful. It seems very accurate for what it is. I like the size because I make a huge mess and need all the bench space I have.Well I finally decided to just splash out, if I'm going to spend serious time I should not waste it fiddling with out of date or sub standard stuff, my bench PSU is feeble too so I just went whole hog and got these.

I'm just a hobbyist (but did study electronics for two years full time before I ended up in software so I'm not really a novice) but always like to have something a bit better than I might actually need. I've been idle with this subject for a long time and only the past year or so begin to spend more serious time.good choice, one day I will get 6 1/2 or 7 1/2 digit Keithly but bench scopes can be handy just to keep things moving.

My next purchase will be a good LCR
I'll look for that book, thanks.Nice, I suggest for reading: electronic fundamentals by Floyd, many of us love the Floyd stuff. It’s written for techs and engineers alike with a nice foundation. After that electronic devices by same author.
The “feeble” tools of today would have been an amazing godsend when I started. Much of this “hobby” grade stuff is actually very good. I take my Flukes out to impress clients but when I’m working I have $20 meters that work just as well. Who needs 7 digits to check for bridging and basic troubleshooting? The nice stuff comes out only when I’m doing a particularly challenging analog issue(s). Most times it’s continuity, diodes, voltage, current and resistance... Digital circuits are especially easy in that sense. I don’t trust even LCRs to measure correctly parasitic inductance in things or other critical problems.
I remember starting with a giant analog multimeter which was really bad.
Good units and popular here in NZ where we are the distributor.Well I finally decided to just splash out, if I'm going to spend serious time I should not waste it fiddling with out of date or sub standard stuff, my bench PSU is feeble too so I just went whole hog and got these.

Well many thanks for this info, I will check the firmware and I think the scope also has slightly old firmware, I got about two years ago and just tinkered with it really, I'm always cautious about firmware updates that I don't "need" yet too, but I guess these are pretty safe to do.Good units and popular here in NZ where we are the distributor.
For the bench meter, when you get it check the firmware version and update to the latest from here:

For the PSU be careful with any regenerative loads and when necessary use a beefy series diode on the output ....that's about their only weakness but little different to most other PSU's.
If you have the 4ch X-E DSO there's a recent FW update for these too, an OS update and a firmware. Install both to enable the new features:
